WlCK-TUBE.

SPECIFICATION forming part of Letters Patent No. 257,021, dated April25, 1882.

Application filed March 17, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. KINNEY, of Meriden, in the county of NewHaven and State of Connecticut, have invented new Improvements inWielcTubes; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure], a sectional side view; Fig. 2, an edge view; Fig. 3, a topview, illustrating the method of making the tongues a I); Fig. 4, aperspective view of the cap from the under side.

Thisinvcntion relates to an improvement in the construction ofwick-tubes, whereby the use of solder is avoided; and it consists inupsetting the edges of the tube above and below a projection in the capthrough which the tube is passed, with a tongue struck from the cap toextend vertically upon the sides of the tube, as more fully hereinafterdescribed.

Arepresents the usual cap, fitted to be screwed into the collar in theusual manner; 13, the wick'tube, also of usual form. In making the cap,instead of cutting the slot for the tube by removing the metal entirely,as by the usual construction, I cut tongues o b by separating the metalon one side, beginning at l and extending around the end to the point 2on the opposite side, and the other, 1), cutting from the point 3 on oneside around the end and to the point 4 on the opposite side, leaving theside opposite on each uncut. These tongues are turned one to the right,the other to the left, as seen in Fig. 4, opening the slot 01 throughthe bottom of the cap corresponding to the shape of the tube, this(littering from the usual construction in that; the tongues a b areproduced.

The tube has a projection, 6, formed in its edge, so as to extend overthe end of the slot at and form a shoulder, so that the tube will restthereon. Then, after the tube has been inserted intoits slot, I formupon the opposite side a corresponding shoulder, f, close up against theunder side of the bottom of the cap, as seen in Fig. 1. These preventvertical movement of the tube. The tongues a b lying close against theside of the tube, as seen in Fig. 2, hold it against transversemovement. Hence the tube is firmly secured, and without the applica ionof solder.

The projections of are formed in the usual manner for making theseprojections by a punch-like operation from the inside outward, or theymay be otherwise formed, it only being essential to this invention thatthe tube shall be interlocked with the cap to prevent verticalmovementof the tube.

I clain1-- The wick-tube cap A, constructed with the tongues a I),extending vertically one on each side the slot in the cap, combined withthe tube B, introduced into the slot between the said tongues andinterlocked with the cap, substantially as described.
